[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a heater with an air purifier.

[0002]

2. Description of the Related Art Generally, a heater with an air purifier is configured as shown in FIG. That is, 28 is a heater main body with an air purifier, 29 is a blower fan provided on the back of the heater main body 28, and serves both as an air purifier and a fan for the combustion section. Reference numeral 30 denotes an air suction unit, 31 denotes an electrostatic air purifier provided in the air suction unit 30, and 32 denotes a combustion unit.

In this type of heater with an air purifier, by rotating a blower fan 29, indoor air is drawn in from an air suction unit 30 and dust in the air is removed by the air purifier 31. The air is supplied to the room as warm air together with the hot air from the combustion section 32 by the blower fan 29 and is heated.

[0005] As shown in the flowchart of FIG. 5, once the stoppage due to the abnormality of the equipment (hereinafter referred to as “reset”) is determined, the operation of both the combustion unit and the air purifier is stopped, and the reset condition is released. Until the reception of the driving is newly performed.

[0005]

However, in the above-described conventional configuration, the reset operation in the event of an abnormality in the combustion section drives the air purifier. In both cases, the operation is stopped, and in the event of a reset due to an abnormality in the air purifier, the operation of both the combustion unit and the air purifier is stopped even though there is no problem to drive the combustion unit. There was a first challenge.

Further, as a second problem, after the equipment is reset due to an abnormality, even if the abnormality is caused by the combustion part, the air purifier alone cannot be used again for re-operation, and the usability as the air purifier is reduced. However, even if the abnormality is caused by an abnormality of the air purifier, the combustion section alone cannot be used again for re-operation, and the usability as a heater may be poor.

An object of the present invention is to solve the above-mentioned problems and to improve the usability of an air purifier alone and a heater alone.

[0008]

According to the present invention, an operation switch for driving a heater, an air cleaning switch for driving an air purifier, and an instruction from the two switches are provided in order to solve the first conventional problem. An operation determining unit that determines and instructs the operation of the combustion unit and the air purifier based on the operation, a combustion control unit and an air cleaning control unit that controls the combustion unit and the air purifier in response to the instruction, and detects an abnormality of the device. An abnormality detection unit;
A reset determination unit that determines the stop of the operation of the device by an instruction from the abnormality detection unit, and determines whether the abnormality is an abnormality of the combustion unit or an abnormality of the air purifier, and determines whether the abnormality is the abnormality of the combustion unit or the air purifier. A reset judging unit for judging whether to stop or both of them, and a load driving unit for driving and stopping the combustion unit / air purifier in response to an instruction from the reset judging unit. There is a configuration.

Further, in order to solve the second problem, the operation determining section includes a first operation for driving only the air purifier alone, a second operation for driving only the combustion section alone, When the operation and the air purifying switch are operated after the device is stopped by the reset determination unit, the stop of the device is abnormal only in the combustion unit. When only the third operation is received, when only the air purifier is abnormal, only the second operation is received, and when both the combustion unit and the air purifier are abnormal,
The configuration is such that all operations are not accepted.

[0010]

According to the present invention, the air purifier can be used alone in a state where there is no hindrance to drive the air purifier, that is, resetting when the combustion section is abnormal. The air purifier can be used alone in a state of resetting, which drives the combustion unit without any trouble, and the usability of the air purifier alone and the heater alone is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, 1 is a lock-type operation switch, 2 is a non-lock type air purifying switch, 8 is an operation discriminator that determines an operation state based on instructions from the switches 1 and 2, and 9 is a combustion controller. Reference numeral 10 denotes an air purifying control unit.
The operation of the combustion unit 5, the blower fan 6, and the air purifier 7 is controlled.

Reference numeral 3 denotes an abnormality detecting unit for detecting an abnormality of the device. A reset determining unit 11 determines reset based on an instruction from the abnormality detecting unit 3, and a reset determining unit 12 determines what the reset content is. And the combustion unit 5 and the air purifier 7
Which operation should be stopped is determined and an instruction is given.

The operation of the above configuration will be described with reference to FIG. First, an operation of refueling reset which occurs due to abnormality of the combustion unit, for example, shortage of liquid fuel will be described. First, the abnormality detection unit 3 detects an abnormality due to a shortage of liquid fuel, and the reset determination unit 11 determines reset in step 14. Then, the reset judging unit 12 judges in step 15 whether or not the reset is caused by the abnormality of the combustion unit. Since the abnormality of the combustion unit is caused by the shortage of the liquid fuel, the process proceeds to step 18. Further, in step 18, since the shortage of the liquid fuel does not hinder the operation of the air purifier, the process proceeds to step 19, where the combustion unit is stopped, and the operation is switched to the single operation of the air purifier alone.

The above-described reset determination is not limited to the refueling reset, but may be performed for all resets. The same applies to resets due to abnormalities in the combustion unit other than the refueling reset.

In the case of a reset in which only the air purifier is abnormal and there is no abnormality in combustion, it is determined in step 15 that there is no abnormality in the combustion section, and in step 16 it is determined that there is abnormality in the air purifier. At 17, the operation of only the combustion section is performed while the air purifier remains stopped. However, depending on the configuration of the heater equipped with an air purifier, this determination may be such that an abnormality in the air purifier affects the combustion unit, and in such a case, it is assumed that the operation of only the combustion unit is not performed.

Next, regarding resetting from an abnormality related to both the air purifier and the combustion unit, it is determined in step 15 that there is an abnormality in the combustion unit, and in step 18 it is determined that there is an abnormality in the air purifier. In step 20, the air purifier
The operation of both combustion units is stopped.

Next, referring to FIG. 3, a description will be given of a restart operation after the device is once reset due to some abnormality.
First, in the case of a reset due to an abnormality in the combustion unit, for example, a shortage of liquid fuel, the process proceeds from step 21 to step 22. Then, in step 22, it is determined whether or not the reset is due to an abnormality in the combustion section. Step 2
In step 5, since there is no abnormality in the operation of the air purifier due to the shortage of the liquid fuel, the process proceeds to step 26 to prohibit the operation of the combustion unit, and only the air purifier alone driving only the air purifier alone is operated. Acceptance of

The determination of the reset as described above is not limited to the refueling reset, and may be performed for all resets. The same applies to resets due to abnormalities in the combustion unit other than the refueling reset.

In the case of a reset in which only the air purifier is abnormal and there is no abnormality in combustion, it is determined in step 22 that there is no abnormality in the combustion section, and in step 23 it is determined that there is abnormality in the air purifier. At 24, the operation acceptance of the air purifier is prohibited, and only the operation of driving the combustion section alone is accepted. However, depending on the configuration of the heater with an air purifier, this determination may be made such that an abnormality in the air purifier affects the combustion unit, and in that case, the operation of the combustion unit is not performed.

As for the reset from the abnormality in both the air purifier and the combustion section, it is determined in step 22 that there is an abnormality in the combustion section, and in step 25 it is determined that there is an abnormality in the air purifier. The operation of both the air purifier and the combustion unit is prohibited and operation is not accepted until the reset condition is canceled.

[0021]

As described above, the control device for a heater with an air purifier according to the present invention, such as in the case of refueling reset described in the embodiment, can be used for the air purifier even in the season when heating is not required, for example. When the air purifier is used, it can be used even in a state where the liquid fuel is insufficient. It can be used and has the effect of improving usability as an air purifier alone.

Also, in a season in which heating is required, resetting due to an abnormality of the air purifier, which is used for driving the combustion unit, can be used as a single combustion unit when there is no hindrance to operate the combustion unit. This has the effect of improving the usability.
